City Portfolio
• 13 departments
• 800 employees
• 60 facilities
• 400 vehicles
• 4,000 streetlights
• 30 City-maintained traffic intersections
• Water treatment and distribution system
565,722 total sq ft
475,000 sq ft in BBC
200+ kW on-site renewables
35 City-installed electric vehicle charging stations
2030 Sustainability Goals – City Operations
Policy:
• 100% of City development investments meet a standard
set for sustainable development, and City promotes and
encourages sustainable development by others
• 100% of applicable City policies incorporate the
principles of sustainability
• All city facilities constructed or renovated shall meet
current Leadership in Energy and Environmental Design
(LEED) standards or equivalent, unless cost prohibitive
based on Return on Investment (ROI) or cost/benefit
Energy and air quality:
• 60% reduced City facility energy consumption per
square foot (2007 baseline)
• 100% of electricity and natural gas sourced from
renewable sources for City facilities and exterior
lighting infrastructure
• 80% reduction in greenhouse gas emissions; 100%
of remaining emissions offset (2007 baseline)
• 80% production of energy for City facilities from
renewable energy sources
• 100% fossil fuel-free staff vehicles and 40% reduction
for other exempt vehicles (non-passenger emergency
response, etc.) [Based on available technologies and
cost effectiveness] (2007 baseline)
• All City facilities zero net energy consumption, if
feasible based on Return on Investment (ROI) or
cost/benefit analysis
Materials management:
• Achieve a rate of construction material consumption that
meets internal standards for sustainability
• 100% of all inputs purchased by the City are sourced
from sustainable sources or meet internally established
criteria (e.g., zero waste, zero toxins) where
technologically and financially feasible
• Zero toxic emissions
• 100% recycling of waste from City operations
• Zero construction and maintenance waste (no waste
from construction and maintenance activities is sent to
landfill). May be accomplished via public/private
partnerships
Natural Resources:
• 25% reduction in water consumption by City
facilities against established baseline (including
re-use and other measures) (2007 baseline)
Building Milestones
• New construction & renovation
• Operations & Maintenance
• Related Policy Opportunities
Milestone – New Construction & Renovation
• Policy
– LEED useful for design, but…
– Energy modeling
– 3rd party commissioning
Milestone – New Construction & Renovation
• Design
– Must marry designers with operators
Milestone – New Construction & Renovation
• Renovations (ren-uh-veyt)
– “to restore to good condition; make new or as if new again; repair”
– “to reinvigorate; refresh, revive”
• Shute Park Library BBC Showcase Project
Before
Milestone – New Construction & Renovation
• Shute Park Library BBC Showcase Project
After
Milestone – New Construction & Renovation
• Shute Park Library BBC Showcase Project
Pre- and post-remodel:
Milestone – Operations & Maintenance
• Policy
– 3rd party commissioning
– How buildings are maintained –focus on energy management, occupant behavior
• Operations
– EMP prescribes process, calendar
– Controls
– Data, facility energy use tracking, reporting
Milestone – Operations & Maintenance
• Seasonal maintenance opportunities
• Shute Park Aquatic Center
Milestone – Related Policy Opportunities
• Dark sky and energy efficient lighting
Thank You“The City of Hillsboro envisions a sustainable future, in which the City responsibly satisfies the needs of its citizens, provides a healthy and satisfying work environment for its employees and minimizes its impact on the physical environment of the community”

64 unit elderly community in Framingham, MA
2010 – refinancing planned to reduce loan rate and replace kitchens and baths
Energy Audit identified:
Poor insulation
Drafty windows
Atmospheric boilers
Inefficient interior lighting
High maintenance site lighting
High water and sewer charges
Saxonville Village
Voluntary energy audit informed owner of tangible value-add opportunities that could be funded from refinancing proceeds.

Reserve Accounts
Bank Controlled Replacement Reserve Account
$576,000
In general, this account can be used to help defray the costs of replacing the project’s capital items in accordance with the Regulatory Agreement.
Winn Controlled Replacement Reserve Account
$424,000
The PCNA outlines the replacement cost of certain capital items; but not energy efficient improvements. Winn saw the opportunity to achieve utility savings by voluntarily replacing certain capital items with more efficient alternatives.

Dedicated Reserves for Energy Efficiency
Apartment Interiors. Replace kitchen and bathroom faucet aerators, shower heads,and toilets, saving of approximately $13,000 per year
Building Envelope. Save approximately $18,000 per year by installing new energy star windows and sliders; and insulting and air sealing the attic.
Heating and Plumbing. Replace the heating boilers with new high efficiency equipmentand replace the unit controls and thermostats with electronic control valves for baseboardzones, saving approximately $12,000 per year.
Electrical. Replace exterior ground lighting with compact fluorescent lighting,replace the exterior pole lighting with LED pole lighting, yielding $6,500 per year of savings.
$424,000 invested yields $50,000 in annual savings = 8.5 year simple payback
